Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Golfers face difficulties in tracking the falling point and trajectory of a golf ball due to its high speed, making it challenging to assess the ball's quality, such as fade or draw, after hitting.
Innovation Solution
An electronic device equipped with a trajectory calculation unit, azimuth sensor, and control unit calculates the ball's trajectory and falling point using initial physical quantities, golf course map information, and position data, allowing for accurate display on a connected device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the golfer visually checks the golf ball after hitting, then the golfer can assess the shot quality, but the golf ball moves at high speed making it difficult to track
Solution Approach 1:
The patent introduces an electronic device as an intermediary between the golfer and the golf ball. This device includes sensors (radar, camera, GPS) that detect and track the ball's trajectory, speed, and position, then transmits this data to a display device. The intermediary electronic system bridges the gap created by the ball's high speed, allowing accurate tracking without requiring the golfer to visually follow the fast-moving ball.
Solution Approach 2:
The patent replaces the golfer's visual tracking system with an electronic measurement and communication system. Instead of relying on human eyes and brain to track the ball, the system uses radar sensors, cameras, GPS receivers, and processors to automatically detect, calculate, and display trajectory data. This substitution of mechanical/optical human perception with electronic systems enables accurate tracking of high-speed ball motion.
2Loss of information
If the golfer tracks the ball trajectory manually, then the golfer can assess shot quality, but it is difficult to check the trajectory and falling point accurately
Solution Approach 1:
The patent segments the trajectory tracking function into multiple specialized components: radar sensors for detecting ball position and speed, cameras for visual tracking, GPS receivers for location data, and processors for calculating trajectory parameters. Each component handles a specific aspect of trajectory detection, and their results are integrated to provide complete trajectory information including falling point and shot quality assessment.
Solution Approach 2:
The electronic device acts as an intermediary that automatically captures, processes, and transmits trajectory information. The sensors detect ball motion, the processor calculates trajectory parameters including falling point coordinates, and the display device presents this information to the golfer. This intermediary system eliminates the difficulty of manual trajectory detection and preserves complete trajectory information.
3Loss of information
If the golfer uses electronic assistance to track the ball, then trajectory information is provided, but the device must be portable and easy to carry
Solution Approach 1:
The electronic device is designed as a multi-functional portable system that combines radar sensing, camera imaging, GPS location tracking, wireless communication, and trajectory calculation in a single integrated unit. This universal device can perform multiple functions (detection, measurement, communication, display) without requiring separate equipment, thereby reducing overall system complexity and improving portability while maintaining complete trajectory information capability.
